Title: Improvements in or relating to counting apparatus
IPC: G01P1/12
Filed: 1953-07-08
Abstract: 775,659. Counting-apparatus; accelerometers. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES O.N.E.R.A. July 8, 1953 [July 11, 1952], No. 18918/53. Classes 106 (1) and 106 (3). Apparatus for counting the number of times, during a given period of time, a variable physical magnitude rises from below a predetermined value to above a predetermined maximum limit value is characterized in that a detector device responsive to any variation of said physical magnitude is arranged to operate a counting device only when said magnitude, has both exceeded the said maximum limit value and dropped below the minimum limit value since completion of the previous step of the counting device. As applied to an accelerometer, a weight 1, Fig. 2, in a container 3 is connected through a shaft to a conductor member 12, the sloping surface of which co-operates with one or more pairs of wiper contacts 8, 10 connected in the circuit of a counter 2 and a battery 5. The arrangement is such that when the acceleration reaches a predetermined minimum value the  member 12 abuts the wiper 10 but as the switch 11, 11a is open the counter 2 is not actuated. When the acceleration is sufficient to cause.the member 12 to meet the wiper 8 the counter 2 is actuated and the switch 11, 11a is closed so that the acceleration must fall below the minimum value before the counter can again be actuated and vibrations which cause a fluctuation about the higher value are not registered. The fixed wiper contacts 8, 10 are preferably adjustably located on a base 14, Fig. 3. The contact member 12 is embedded in an insulating piece 13. In another example, Fig. 5 (not shown); the contact member 12 projects from the surface of the insulating piece and the movement of the wipers towards said piece is limited by an abutment.

Abstract: 438,468. Light - current relays. CENTRAL NEWS, Ltd., and DAVIES, C. C., 5, New Bridge Street, London. June 27, 1934, No. 19048. [Class 38 (v)] A double-current centred relay of the telegraph type has two permanent polarizing magnets arranged to be magnetically in shunt with the opposite limbs of a core on which are mounted the oppositely-wound series-connected energizing windings, an armature lightly biassed to a central position in an air gap of the core being attached to the core with interposed non-magnetic material, the armature carrying contacts adapted to co-operate with fixed contacts at the side and the polarizing magnets being separated from the core limbs by non-magnetic gaps but being arranged to induce similar and substantially equal polarization at the poles of the core on either side of the air gap in which the armature is situated. As shown in Figs. 1 and 3, the operating windings 6, 7 are oppositely wound and mounted on the two vertical members 1, 1<a>, of a rectangular laminated core having an air gap 3 in its upper cross limb. The operating armature consisting of a resilient blade 4 passes upwardly through the air gap, its lower end being held in. a non-magnetic block mounted in the lower cross-limb 2 of the laminated core. Two permanent polarizing magnets 40 are mounted, one behind and at a slight distance from each limb 1, 1<a> of the laminated core having like poles at adjacent ends and so arranged as to induce substantially similar magnetization in the two poles of the laminated core on opposite sides of the gap 3. The permanent magnets may be adjusted in relation to the laminated core to vary the operating characteristics of the relay. The upper end of the core bears contact tips 8, 9 adapted to engage one or other of a pair of relatively fixed contacts 10, 11 in accordance with the direction of current in the energizing coils. Normally the resilience of the reed armature lightly biasses it to a central non- contacting position. The contacts 10, 11 are carried at the ends of adjusting screws 20, 21 which may be clamped in adjusted position by screws 26, 27.

Abstract: 1,218,184. After-treated and grafted polymers by metallation. DUNLOP CO. Ltd. 24 April, 1968 [26 April, 1967], No. 19122/67. Headings C3G and C3P. Graft polymers or polymers having functional groups along the backbone chain are obtained by polymerizing in an inert organic solvent a first monomer with metallic lithium or an organolithium catalyst, followed by the addition of a ditertiary diamine and an organolithium compound and/or a complex of an organolithium/ditertiary diamine complex, in amounts such that the molar ratio of diamine to lithium is at least 1:1, whereby metallation of the polymer takes place along its backbone chain, whereafter a second monomer or a reactant which will provide functional groups on the backbone chain is reacted with the metallated polymer. Suitable reagents to provide functional groups are CO 2  (COOH groups), phosgene (COCl groups), alkylene oxide (OH groups) and alkylene sulphide (SH groups). The first monomer is suitably a conjugated diene with or without other monomers, while a very wide variety of possible second monomers are mentioned. A small amount of block polymerization may take place in addition to the graft polymerization. In the Examples (1-5) isoprene is polymerized using n-butyl lithium/cyclohexane, metallation is effected using N,N,N<SP>1</SP>,N<SP>1</SP>-tetramethylethylene diamine (TMED) and a 1:1 complex of n-butyl lithium and TMED, and styrene is copolymerized on to the metallated polymer, and (6) isoprene is polymerized as in (1-5), n-butyl-lithium and TMED added, and N-phenylmaleimide copolymerized on to the metallated polymer.
